level-ordered

A wrapper for level that keeps inserted items ordered.

All items should be in JSON form.

Usage

// create/access database
const testDB = await Database.access('dbName', 'collectionName');

// insert items
await testDB.insert({ val: 'one' }, { val: 'two' }, { val: 'three' });

// get all items
const allItems = await testDB.getAll();
allItems.map(({ val }) => val); // ['one', 'two', 'three']

// get last item
await testDB.getLastItem(); // { val: 'three' }

// delete item: { val: 'two' }
const filterFunc = ({ val }) => val === 'two';
await testDB.deleteBy(filterFunc);
await testDB.getAll(filterFunc); // []
